Description Robert Fries 2015-04-13 16:25:12 UTC

Application: kmail (4.14.6)
KDE Platform Version: 4.14.6
Qt Version: 4.8.6
Operating System: Linux 3.19.3-200.fc21.x86_64 x86_64
Distribution: "Fedora release 21 (Twenty One)"

-- Information about the crash:
- What I was doing when the application crashed:
Clicked on an email in an Imap inbox.  The email I clicked on was shows as the parent of another more recent email.  
- Unusual behavior I noticed:
I tried to restart kmail after the crash and it immediately crashed with a message to the effect that it could not access the collection.  I then ran "akonadict restart" after which I was able to restart kmail and access the email that caused the problem before.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KMail (kmail), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Denis Kurz 2017-06-23 20:04:47 UTC

This bug has never been confirmed for a KDE PIM version that is based on KDE Frameworks (5.x). Those versions differ significantly from the old 4.x series. Therefore, I plan to close it in around two or three months. In the meantime, it is set to WAITINGFORINFO to give reporters the oportunity to check if it is still valid. As soon as someone confirms it for a recent version (at least 5.1, ideally even more recent), I'll gladly reopen it.

Please understand that we lack the manpower to triage bugs reported for versions almost two years beyond their end of life.

Comment 2 Denis Kurz 2018-01-31 16:53:18 UTC

Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.1 aka 15.12, preferably more recent), please open a new one unless it already exists. Thank you for all your input.
